The AFLS provides an accurate air data source and avoids calibration on the aircraft itself. The pitot and static measurement is realized with a Prandtl probe. The probe is mounted on a cardan joint to compensate the AOA and AOS. The cardan joint is equipted with two Hall effect sensors in order to measure the AOA and AOS. Attaching the AFLS on an aircraft is accomplished through a 40 mm carbon tube. The AFLS is tested up to a TAS of 380 kt.
